Title: Colour coating process
Inventor: ENGELHARDT DAVID ROSS
IPC: B05D5/06
Filed: 1981-12-24

Title: Cellulose sulfate gel composition
Inventor: ISHII KUNIO
IPC: A23L29/20
Filed: 1982-06-11
Abstract: The physical properties of aqueous gels comprising cellulose sulfate and one or more inorganic alkali metal salts are improved by the addition of one or more other water soluble polymers. The water soluble polymers are typically natural polysaccharides or cellulose derivatives other than cellulose sulfate. The gel can be obtained by dissolving the cellulose sulfate and water-soluble polymer components in water, adding an aqueous solution of the alkali metal salt to form a precipitate, redissolving the precipitate by heating, and then cooling the resulting solution. The thus obtained gel, in comparison with a corresponding composition containing no other water soluble polymer, has a higher gel strength and is a thermally reversible gel. The gel composition has various useful applications such as in the food, toiletry and medical arts, and as a slow-releasing carrier for perfumes or insecticides.

Patent GB-2130451-A (GB)
Title: Current splitter
Inventor: BRIDGER PETER STUART
IPC: G05F3/26
Filed: 1982-11-05
Abstract: A current splitter is formed by two transistors (Q1 and Q2) whose bases are coupled, and whose emitters are commoned to a current source (CS). One transistor (Q1) also has its base and collector coupled. Assuming identical transistors, the current IIN due to the current source (CS) is split equally between the two collector circuits, which thus produce output currents whose values are substantially independent of the load impedances and voltages when the circuit remains linear. With a number n of transistors the current can be split equally between them, or split according to ratios dependent on transistor characteristics or collector connections. <IMAGE>

Patent GB-2134972-A (GB)
Title: Hinge assembly
Inventor: BARTMANN NICHOLAS
IPC: B60J7/16
Filed: 1983-12-08
Abstract: A hinge assembly 3 for a sunroof panel 4 is located with its effective transverse pivot axis W only slightly rearward of the vertical plane containing the front edge 4a of the panel 4, so as to minimise compressive wear on the elastomer panel seal 10 when the panel 4 is opened. For example, a metal channel 15 secured to the flap has a rounded forward edge 35 fitting in a groove 12, and held thereby by elasticity of seal 10, optionally plus channel elasticity. A protective cowl 13 can protect this arrangement, and is capable of being pulled back around pivot Y by a finger pull in space S against over-centre mounting X-Y-Z. Such control movement also affects the securing of channel 15 to the pane 4, whereby channel 15 falls downwards to free the pivot 35/12 and thus allow the hinge assembly to be removed. <IMAGE>
Patent GB-2132857-A (GB)
Title: Voice encryption and decryption system
Inventor: AKAIWA YOSHIHIKO
IPC: H04K1/04
Filed: 1983-12-09
Abstract: A random number sequence is generated and, in response to a discrete value produced from the sequence, an analog signal to be transmitted is scrambled to produce a first analog signal. The first analog signal and a second discrete signal produced by enciphering the random number sequence is combined, the composite signal being sent out to a receiver. At the receiver, a procedure opposite to that performed by the transmitter for combining the first and second signals occurs to separate the first analog signal and the second discrete signal. Decryption opposite to the encryption at the transmitter proceeds in response to a discrete value which is produced from a signal provided by deciphering the second discrete signal. <IMAGE>

Title: Adjustable torsionally soft couplings
Inventor: TAYLOR IVAN
IPC: F16D3/04
Filed: 1984-06-08
Abstract: A torsionally soft coupling (10) between input (11) and output (12) members, is rendered adjustable in any of four physical parameters, namely radius (Rx, Ry) of attachment of links (4, 5), total lengths (Lx + Ly) of links, ratio of link lengths (Lx/Ly) and mass (m) acting at the pivot point.

Title: Flow contoured electron capture detector cell
Inventor: WELLS GREGORY JAMES
IPC: G01N27/66
Filed: 1984-08-08
Abstract: A small volume electron capture detector has a cylindrical cell 120 inside which there is provided a generally funnel-shaped insert structure 130 having a cup-shaped section and a cylindrical section, and a radioactive foil 125. The rims of the cup-shaped section nearly touch the inner walls of the cell 120 so as to separate the active volume from the areas at the top corners of the cell 120 which are not actively swept by the carrier gas, thus reducing the tailing of chromatographic peaks. Make-up gas entering through ports 122 sweeps the sample only into the central region of the cell. Contamination of foil 125 by the sample is also reduced. An alternative structure (230) is disclosed (Fig 4). <IMAGE>
